Abstract

In the microsporocytes of Pandanus odoratissimus, cytokinesis is succesive with centrifugal cleavage in both the meiotic divisions. The dyads move apart from each other after the first division, and the microspores likewise after the second division, so that only monads are formed at the end of meiosis. Although no trace of callose wall is found any stage around the microsporocyte or microspore, fertile, monocolpate pollen with well-developed, spinescent exine develops, and is shed at the two-celled stage
